No output from 3rd channel

No output from 3rd channel

2010-03-31 by Gino

I know this topic has been touched on before, but I couldn't find any conclusive info on a fix.  I have a plain EII that either has a dead voice or channel not sure how to distiguish the two?  Basically if I go into special fucntions and disable channel 3 the EII is playable.   With channel three on,  every 8th note played in succession is silent. Does that mean I have a dead voice or channel? How should I proceed? trace everyhting in the signal path to channel 3? Any hints on where to start would be greatly appreciated.  Thanks

My first bit of advice would be to re-seat all the IC's on the main board.
Do Not pull them out..
First, with a very fine screwdriver, gently pry each side of the IC up a few mm. Then Press the whole IC back into it's IC mount.
- Repeat, untill ALL IC's have been done.
(This cleans the contacts between the IC and it's Socket)
My EII had a unreliable voice, and this solved it.
If this does not work.. then.
You could start by swapping IC's from the dead voice (3)�to another voice.
I'd start with the VCF.
If the prob goes to another voice, then you've found the problem.
Don't do any of these things with the EII Powered up or even plugged in. (Safety!)

Mike,
Thanks, that sounds like a good place to start.� EII dispalys, are they supposed to be backlit? Mine is not, I guess thats my next�issue to resolve after the voice is fixed.
Came with an extensive library over 200 disks that I am going thru.� I really like to sounds and the feel of some of the arpegs and stored sequences.�
Regards,
G

Yes, they are backlit.
The EL foil degrades over time.
If you turn off the lights, and are in a dark place with the EII on, does the display glow faintly?
if so, it prob just needs new EL foil. This can be bought off sellers on ebay. I did this for mine, and it's nice and bright now.
eg.
Sometimes the inverter dies, but I think 98% of the time, it'll be the EL foil.
Best of luck.
Mike
